After trailing 28-21 at halftime, the Hokies tied the game at 36 when Devin Wilson’s 3-pointer with 12:16 remaining capped an 11-2 run.

Tokoto hit a 3-pointer for the Tar Heels to end the run, and North Carolina did not trail again.

Virginia Tech cut the lead to 58-54 on a 3-pointer by Eddie with 40 seconds left, and then McDonald missed two free throws with 35.8 seconds to go, giving the Hokies a chance.
